Schmidt SON 28 Rim Brake 9x100mm Front Dynamo Hub 32H Black Anodized

The SON 28 is a universally approved hub dynamo for all wheel sizes 16 “to 29”. It achieves its nominal output in the 28 inch wheel at approx. 16 km / h (SONdelux 19 km / h). It is therefore recommended if you need a lot of light when driving slowly or if you want to operate other devices or charge their batteries.
The new SON 28 is similar in structure and appearance to the SONdelux. In the standard version (non-disc), the flange distance and the bearing distance are increased by 12 mm and 10 mm, respectively, compared to the SONdelux.
Compared to the SON 28 classic (model year 2000 to 2011) the idling losses could be reduced by approx. 15% and the weight by 140 g
